Pulley Upgrade

Looking for a recommendation on a pulley upgrade. Also, is this a simple do it yourself upgrade?

Thanks in advance for any and all help.

Hardest part is getting a pulley puller and press. Since a Whipple needs neither and provides more power I skipped the pulley and tune. Some just go to a TT from the start.
 
It's not to difficult. I did my own. Bob Ida pulley, Get a SCT tuner and tune From Torrie / Unleashed tuning , He's a site sponsor.
 
The Ford Racing upgrade is a ready made package with the tune included. Need to pull the supercharger, use puller, press on new pulley, re-mount supercharger. Belts get to be a problem. There's a bunch of old posts about this. Do a search.
 
Yeah, the answers here are all similar. It's not that hard but it does take some specialized tools that you may not have - namely a pulley puller and a press. For the puller, unlike other Ford OEM blowers, there is no threaded center hole - thus the need for a special puller. With the pulley off, you then need to remove the snout of the SC so that you can place it in a press with a round 1" stock on the inside of the snout to press against. Next is re-sealing/assembling the SC and then installing the shims on the power steering pump so that the OEM belt doesn't have too much slack with the smaller pulley. I too like the Ford Racing Kit because it includes the pulley, tuner, tune, SC oil to re-fill the SC, sealant to re-assemble the SC, and the shims (spacers) for the power steering pump.

How many people used shims? I used the stock belt, no shims, 13000 miles no issues..

The Ford Racing Kit and the now discontinued Kenne Bell snout kit both came with shims. (In fact the KB kit came with two sets of shims and a table of which to use depending on the pulley size you used.) If you look at the OEM belt tensioner when a new pulley is installed (with no shims), it is at it limit... but it still has some motion. With the shims in place, the tensioner is back to it's neutral (full range) position. The shims are a nice touch. They are not that easy to install and we've seen our share of Ford Racing Kit installs without the shims. Obvioulsy some installers are discarding them to save time. We don't.
 
I had mine done with the Ford Racing System pulley and tune and the Ford Exhaust.

I just did a pulley and tune a couple of weeks ago. I used Torrie's tuner and pulley. It does not come with shims, but you do not need them (I asked a bunch of people beforehand and they all agreed that shims aren't necessary). The benefit of Torrie's tuner is that you can put in different tunes (i.e. if I subsequnetly fitheaders he can e-mail me a new custom tune) whereas I think the Ford package is one configuration only?
The Ford manual tells you to pull the interior acccess plate to permit getting at the belt to de-tension it, but, once again, everyone said this is not necessary. I did mine at the same time as an oil change so I had the belly pan panels off to allow access to the belt from below. In the end I didn't need to touch the belt at all - if you are careful taking off the blower the belt just sits there, and when you re-fit the blower you can slide the snout under the belt and then "lever down" on the other end of the supercharger body which causes the pulley to engage the belt and tension it right back up. The configuration of the blower gasket is such that you do not damage or compromise any sealing surface with this method - all very simple. With oil change the whole job took about 4-4.5 hours. THe only trick is to know someone with a hydraulic press to pull and replace the pulley - I used a buddy's, but a Harbor Freight press is perfect for this job and costs only around $120.
THe work is well worth the effort - the extra HP makes the car a whole lot more fun, although I can fully believe the folk who tell me that once you've tasted an extra 100hp then you soon want to move onto a big-ass Whipple or TT.
 
Has anyone had a problem with getting their car inspected after the Tune? I get a "Not ready" notice. I was told to restore the original Tune and drive it so it would pass inspection.

Ain't that the truth!
